The invention further resides in the provision of certain novel and advantageous surfacetreating and dusting elements constituting detachable and replaceable parts of the device.

WVith reference to thedrawings, and particularly to Figs. 1 to 3. inclusive, the device includes a casing which may be advantageously formed .of two elements 1 and 2, shown respectively in'Figs. 1 and 2, struck up from sheet metal, the part 1 being of substantially rectangular box form open at one side and having its opposite side formed asclearly shown-in Fig. 8, to provide a nor mally convexed flexible section 3. The member 2 consisting of a. substantially'flat plate having a central depression 4 and at each end an offset 5, and also at the side edges depending flanges 6,'is adapted to fit within the member 1 as shown in Fig. 3 to form a casing. closed with the exception of a filling aperture 7 at the bottom of the depression 4. The member 2 may be secured in the,

member 1 by soldering or any other suitable means. I

When secured within the member 1 as shown in Fig; 3, the oii'setportions 5 of the member 2 each form what in effect are two separate pockets, one pocket lying inside the cover 2and adapted for reception of weight members 8, the other chamber 9 lying externally of the cover member 2 and adapted for reception of applicator or floor-treating elements, as hereinafter described. Itwill be noted that the inset flexible portion 3 of the casing member 1 provides shoulders 10, 10, at the ends of the casing behind which the weights 8 are set and which function to retain the weights in their pockets at the ends of the casing. In addition to the parts pre vionsly mentioned, the casing, composed of the parts 1 and 2, comprises a pair of tr'unnion members 11 which may take the form of separate elements lodged in apertures in the sides of the casing member 1, being secured therein in suchmanner as to provide a watertight joint. These trunnions .project beyond the outer side faces of the casing and provide means for attaching a handle, as hereinafter more fully described. The side flanges 6 of the member 2, when the latter member is assembled with the member 1, extend over the edges and project down the outer side faces of themember 1. r

The member 2 also embodies a discharge port 12, and valve mechanism is provided as shown in Fig. 8 for normally closing this dischargeport. The valve mechanism in the present instance is supported upon an arm13 which is secured to the inner side of thepart 2, one end of said arm underly-' ing the filler opening 7, and being apertured in registry'with the filler opening, the sides of this aperture being threaded for reception of a threaded filler "plug 14 which may be threaded into the opening from the outside of the casing, the opening being sealed by means of a rubber or other suitable gasket 15. f

. The operating parts of the valve comprise I an arm 16 pivotally securedat 17 to an arm 18 projecting at right angles from the arm 13, the arm 16 having at one end a'relatively soft conical 'valve element 19 which effectively closes the discharge port 12, as shown Ill in Fig. 8. the other end of the arm 16 nor-- inallv lying against the flexible and normally eiiteuded side 3 of the casing, also as shown in Fig. 8. A spring 20 is also provided which engages the end of the arm 16 and the outer end of the arm 18, and exerts a force tending; to retain the arm 16 in such a. manner that the valve element- 19 norinallv closes the port 12.

It has been found that an effective seal at the discharge port can be obtained by forming the conical. valve element 19 of lead or similar soft metal, and thereafter pressing it firmly into the port 12 that it may conform to the shape of the latter. ith the mechanism described, it will be appan cut that: pressure upon the outside of the flexible portion 3 of the casing" will result in an inward flexing of the latter and simultaneously oscillate the arm 16 so as to open the discharge port 12.

Our device further and preferably coinprises a pair oi? l'loortreating elcinents one of which shown in, perspective in Fig. 5, so formed as to be capable of insertion in the pockets 9 of the casing previously described. These elements conuirise in the present lllSll'LllC'. a substantially rectangular block .21 of such size as to lit the pockets l) of the casing with a fair amount of snugness, and one side of this block 21 is n'eferably convened so that when a felt, or other strip 22, is suitably secured on its outer surface, the outer face of such felt given a convexed form, as clearly illustrated. 'lhese felt strips may be secured to the blocks by means for example of adhesive or by sewing to a strip which extends around the back of each of the blocks, as illustrated in the present instance, in Fig. 8.

The device further comprises a substantially open-sided box-like pad or hood 2;, best shown in Fig. 6, which is adapted to receive the casing and to extend over five sides thereof, including the flexible side 3. is clearly illustrated. the pad 23 is pro vilded with apertures 2% for passage therethrouuh of the trunnions 11 previously described. In practice, it is preferable to use in conjunction with the applicator elements 21:'22 and the hood 23, a polishing cloth which preferably extends over and around the hood 23 longitudinally of the casing and also over the tops of the applicator pads 22, the ends of this polishing cloth or fabric strip being confined within the pockets 9 by the said applicators, as clearly illustrated in Fig. 8. This cloth may be replaced when soiled, and not only provides for a clean and soft polishing surface, but helps to retain the hood 23 in position In conjunction with the aforedescribed elements, we preferably provide with our device a floor-treatingelement of the type shown in Fig. 7 in the form of a brush or other element. This element. comprises in the present instance a flat rectangular base 26 which forms the backing for the bristles of the brush and is of substantially the same length and width as the casing, At the ends of this base 26, we may provide two fabric strips or flaps 27 which as shown in .l ig. 8 may be carried up and over the ap plicator rnulswvitl'i the ends thereof conlined umlerneath the latter within the pockets 9 whereby the brush element is firm- 1y held in position on one side of the casinn.

In addition to the brush or similar element. we may provide a dust pad 28, see Fin. 9, which may be provided with laps similar to the flaps 27 of the {lifOl'QdBFiClllJGtl brush. element, or may have the binding tapes or strips 29, see l lip. 9, which may pass up over the applicator pads and be fastened together by means of a snap or other suitable catch 30 whereby the dust pad is held on the casing.

its an alternative method of applying the l'loor- -treating devices, we may form the lat ter as shown in Fig. ll), with elements 33 at the back adapted to lit and be frictionally retained in the pockets 9 after the manner of the applicator elements 21 In this case, when the brush or other device is to be put into use, the elements 21-22 are removed from the pockets 9 and are replaced by the elen'ients 33 which retain the treating device in position on the casing.

In addition to the parts previously described, we provide a, handle 31 whose lower end is bifurcated and is flexible so as to perniit its being passed over the trunnions 11 on the casing, as clearly shown in Fig. 9, the handle by reason of the flexibility of the bifurcated ends being easily (letachable from the casing; if it is desired to remove the pad or hood 2 The operation of the device will be readilv uilderstood by those familiar with the art. ilith the brush element removed and in a position such that the. applicator pads 21- 22 rest upon the floor or other surface to be treated, a slight pressure upon the flexible top part 3 of the casing will result in an expulsion of the liquid polishing medium in the interior of the casing onto the said surface. The casing is then rociprocated over the surface by means of the handle 31. to distribute the wax, and when the dis tributing operation is completed, a reversal of the casing to the position shown in Fig". 8 permit the use of the reverse padded side of the casing for polishing purposes.

As a final polishing operation, the brush 26 may be attached as previously described, and the device then passed over the floor to afford. the desired lustrous finish.

As a later operation. of maintaining the floors in a clean and dustless condition, the
